Nhanganyaya yekushandiswa kwemafuta analyzer uye sampuli bvunzo

Test method:

Mafuta analyzer anonyanya ane nzira dzinotevera dzokubvisa mafuta: Soxhlet standard extraction, Soxhlet hot extraction, kupisa kunopisa, kuenderera kunoramba kuchiyerera, uye nzira dzakasiyana-siyana dzokubvisa dzinogona kusarudzwa maererano nezvinodiwa zvakasiyana zvevashandisi.

1. Soxhlet chiyero: shanda zvizere maererano neSoxhlet extraction method;

2. Soxhlet thermal extraction: pamusana peSoxhlet standard extraction, kupisa kaviri kunoshandiswa. Mukuwedzera pakupisa kapu yekuchera, inopisawo mutezi mukamuri yekuchera kuti uvandudze kushanda zvakanaka;

3. Thermal extraction: inoreva kushandiswa kwemaviri ekupisa maitiro kuti uchengetedze sampuli mune inopisa inopisa;

4. Kuenderera mberi kuyerera: zvinoreva kuti solenoid valve inogara yakazaruka, uye iyo yakanyungudutswa yakanyungudutswa inoyerera yakananga mumukombe wekupisa kuburikidza nekamuri yekubvisa.

Matanho ekuedza:

1. Isa mafuta analyzer uye ubatanidze pombi.

2. Zvichienderana nezvinodiwa zvekuedza, kuyera sampuli m, uye kuyera yakaoma yakanyungudutsa mukombe mass m0; isa sample musefa bepa cartridge ine chiridzwa, wobva waisa katuriji yebepa resefa mumubati wesample woiisa mukamuri yekudhonza.

3. Edza huwandu hwakakodzera hwekunyungudutsa muimba yekuchera necylinder yakapedza kudzidza, uye isa kapu yekunyungudutsa pane inopisa ndiro.

4. Vhura mvura yakasvibiswa uye shandura chiridzwa. Seta tembiricha yekubvisa, nguva yekubvisa, uye pre-kuomesa nguva. Mushure mekuisa iyo yekudhonza kutenderera nguva mumaseti ehurongwa, tanga bvunzo. Munguva yekuedzwa, iyo inonyungudutsa mukapu yekunyungudutsa inopisa nendiro yekupisa, inoputika uye inodonhedza mucondenser, uye inoyerera ichidzokera kukamuri yekubvisa. Mushure mekunge nguva yakatarwa yekutora nguva yasvika, vheji ye solenoid inovhurwa, uye iyo inonyungudutsa muimba yekuchera inoyerera inopinda mumukombe wekunyungudutsa kuti iite mutsara wekubvisa.

5. Mushure mekuedza, chigadziro chekusimudza chinoderedzwa, mukombe wekunyungudutsa unobviswa, wakaomeswa mubhokisi rekuomeswa, uye unoiswa mu desiccator kuti utonhore kusvika kukushisa kwekamuri, uye mukombe wekunyungudutsa une mafuta asina kuchena unoyerwa m1.

6. Isa chigadziko chakakodzera pandiro yekudziya, vhura solenoid valve inoenderana nenhamba, uye dzorera iyo solvent.

7. Verenga huwandu hwemafuta (verenga wega kana kuisa chiridzwa kuti uverenge)
